package-alternate-name

Arguments: package-designator

Returns the package alternate name of the package specified by package-designator, which can be a package object or a symbol naming a package (keywords are good choices) or the package-name (a string).

The package alternate name is the name that will be used when a package name must be printed as a package qualifier of a symbol when using alternate names is called for because *print-alternate-package-name* is true. The alternate name must be either the package name (as returned by package-name) or one of its nicknames (as returned by package-nicknames). The alternate name is specified when the package is created.

If no alternate name has been specified, then the default alternate name is defined to be the first nickname is the list of nicknames (as returned by package-nicknames) or, if no nicknames are defined, the package name.

The alternate name can only be set when the package is created. Both defpackage and make-package accept additional arguments allowing the alternate name to be specified. (See Extensions to cl:make-package, cl:disassemble, cl:truename, cl:probe-file, cl:open, cl:apropos and cl:defpackage and cl:in-package, both in implementation.htm, for more information on extensions to defpackage and make-package.)

If no alternate name is defined when the package is created, one can be added by recreating the package. The default alternate name, determined as described above, is used as the alternate name if none is defined at package-creation time.
